Abstract
In a combined cycle plant, a device for controlling a combined cycle plant, and a method for starting up a combined cycle plant, the time for starting up the combined cycle plant can be shortened by providing: a gas turbine having a compressor, a combustor, and a turbine; a heat recovery steam generator for generating steam by means of the exhaust heat of exhaust gas from the gas turbine. A steam turbine is driven by the steam generated by the heat recovery steam generator; and a control device is configured to set a standby load for the gas turbine during a start-up continuously to change in accordance with a change in metal temperature of the steam turbine.
